Abstract

The purpose of this study is to determine the effect of IBA plant growth regulators (Indole Butyric Acid)on germination of sugarcane cuttings (Saccharwn o_mcinarum L). The experimental materials include PSJT 941 variety of sugarcane cuttings, soil and manure as medium with 2: 1 ratio. IBA and 50% alcohol is used as treatment. Pest and disease controls used Basudin 60 EC and Dithane M-45. This study uses Randomized Block Design (RAK) with three replicates and each replicate consisted of 2 sample plants. The treatment is as follows: Ko: without treatment, K1: 500 ppm, K2: 1000 ppm, K3: 1500 ppm, K4: 2000 ppm. The study reveals that treatment of K4 IBA solution (2000 ppm)has very significant effect on variables of germination speed, shoot length, number of leaves and number of roots, and significantly different at root length. Administration of IBA solution at concentration of 1500 ppm accelerated germination time of sugar cane cuttings, occurred on the fourth day (fourth). Administration of IBA solution at 2000 ppm gave the highest result which was not different with 1500 ppm concentration on shoot length, leaf number, root length and root number. The higher the concentration of IBA, the higher the shoot length, the number of leaves, the length of the roots and the number of roots of sugar cane produced.

Abstract

The purpose of this research is to determine interaction between composition of growing medium, PGR concentration to growth, influence of composition of growing medium toward growth and harvest of pakchoy. The present study uses factorial randomized group design consisting of two factors with three replicates and 2 sample plants. Factor I is growing medium composition of 3 levels while factor II is a level 3 PGR concentration. The composition of these factors is factor I: M 3 garden soil: 1 manure, M 2 = 2 garden soil: 2 Manure, M 3 = 1 = 1 garden soil: 3 manure. Factor II consists of: K = 2 ml/liter of water, K 2 = 4 ml/liter of water, K = 6 ml / liter of water. Results from this study indicate that the combined treatment of manure and PGR concentration has significant effect on observation of plant length at 28 days of age. However, it does not give real interaction to variables of number of leaves, plant length, and gross at all ages of observation. The use of manure has significant effect on all observation variables. The highest average plant length, leaf number, and highest gross were obtained at the treatment of M 2 3 (2 garden soil: 2 manure). Treatment of PGR concentration had significant effect on all observation variables. Average length of plants, number of leaves, and highest gross were obtained at treatment of K 2 ml / ltr water.

Abstract

The objective of the research is to determine the effect of sawdust and chaff media storage on viability of cocoa (Theobroma cacao L.) seeds. Cocoa seeds’ viability need to be maintained during storage/shipment to planting destination. The research uses simple group randomized design (RAK)consisting of five (5) treatment with three (3)replicates. Assignment of treatment is carried out in randomized trial plots. The varieties tested is F1 hybrid varieties obtained from Indonesia Coffee and Cocoa Research Center. The parameters observed included percentage (amount) of germination, rate of germination, and gross weight of sprouts. The result indicates shows that media storage treatment using sawdust and chaff provides significant effect on the percentage (number) of seeds germinate, sprout and speed or rate of gross weight of cocoa seed sprouts. In addition, control treatment (storage without chaff or sawdust) resulted in the highest percentage (number) of germinated seed, while the highest germination rate and gross weight of sprouts is indicated by treatment of storage with chaff of 100% although not significantly different statistically with 50% chaff.
